The 9K720 Iskander is a mobile short-range ballistic missile system produced and deployed by the Russian military. They travel at a terminal hypersonic speed of 2100–2600 m/s and can reach an altitude of 50 km as they range up to 500 km. The missile systems (Искандер-М) were intended to replace by 2020 the supposedly-obsolete OTR-21 Tochka systems in the Russian military.
